The upper surfaces of the floor members 61, portion'of the floor 62 and the portion 45 of the member 8 are in substantially the same horizontal plane. The top or roof portion 46 is of circular form in plan and has a downwardly depending annular flange 63 to which the curved sides 47 are secured.

Between the sides the flange 63 has secured thereto curved plates 64 which plates, as well as the upper portions of the sides 47, extend above the flange 63. The periphcry of the portion 46 above the flange 63 is offset at 65 and this ofl'set together with the.

upper portion of the sides 47 and plates 64 form a water conducting channel for conducting water from the portions of the member 8 which are located in recesses formed inthe adjacent ends of two bodies by the construction embodied therein which have hereinbefore been fully described. Between the bodies each of the portions of the sides which projects above the flange 63 is provided with a notch 66 which permits the water in the conducting channel to drain to the exterior of the car. The top of the member is preferably in the form of a portion of a sphere the radius of which in any direction is struck from the center of the bearing surface 54. In the present embodiment of the invention the portion 46 is illustrated as having formed therein a transverse water conducting channel 67 which is adapted to conduct water to the notches 66. The plates 40 which are secured to the hood sheets extend downwardly in close proximity with the outer surface of the portion 46 and their lower edges are curved to correspond with the shape of the major portion of the outer surface of the portion 46. These plates will form effective weather seals between the top of the member 8 and the bodies 2 of the car regardless of the positions of the bodies relative to each other or the position of the member 8 relative to the bodies. In Fig. 12 a modification of the weather proofin construction has been illustrated in %ie lower edge portions of the plates may, if desired, be omitted, as shown 'in Fi l3.

fietwcen the member Sand the adjacent ends 3, rollers 68 are provided which are adjustably mounted on the end posts 12 and engage the outer surfaces of the sides 47 of the member 8. Each of the rollers is of substantially the same length as the sides 47 and at its upper end is rotatably mounted in a member 69 which member'69 is loosely mounted in a member 70 secured to the upper end portion of the post and to the plate 35. At its lower end this roller is .rotatably mounted in a member 71 which in turn is loosely mounted in a member 72 secured to the lower end portion of the poet and to the underframe. The members 69 and 71 are each provided with a horizontally disposed web 73 and vertically disposed sides 74 and 75 and vertically disposed ends 76 and 77. To connect the members 69 and 71 together a channel shaped member 78 is provided. the upper end portion of which is secured to the flanges 74, 75 and 76 of the member 69, while the lower end portion is secured to the flanges 74, 75 and 76 of the -member 71.

The members 70 and 72are each provided with a horizontally disposed web 78 which in the case of the member 70 is secured to the plate 35, and in the member 72 is secured to the underframe 4. Each of these members is also provided with vertically disposed side flanges 79 and 80 and end flanges 81 and 82, the flanges 79 and 80 being secured to the web 13 and flange 15 respectively of the end post 12. Between the flanges 81 and 82 each member is provided with a bearing surface 83 which is in substantially the same horizontal plane as the bearing surface 84 of the flange 79.

Beyond the ends of the member 78 the members 69 and 71 are each provided with side flanges 85 having curved bearing surfaces 86, one of which flanges in the member 71 rests on and slidably engages the bearing surface 83 of the member 72 and the other rests on and slidably engages the bearing surfaces 84 of the flange 79 of the member 72. In the member 69 one of the surfaces 86 is adapted to engage the bearing surface '83 of the member 70, and the other surface is adapted to engage the bearing surface 84 lot) of the flange 79 of the member 70. The

Y which is removably mounted on the member 78. These springs are for the purpose of forcing the rollers into close contact with the sides 47 of the member 8 at all times. It will be noted that the member 8. due to the movement of the truck and bodies relative to each other, may be rotated and also caused to swivel and that the rollers 68 will at the same timebe so automatically adjusted that they will maintain weather roof connections between the member 8 an the adj acent car bodies. It will also be noted that the bearing surfaces 86 of the flanges 85 are curved for the purpose of preventing any binding action between the members 69 and 71 and the members 70 and 72 when the member 8 swivels and also to. reduce the friction between these membersto a minimum. It will be noted further that as the member 8 will swivel a greater distance at itsupper portion than at its bottom, the bearing surface 83 of the member 7 O is of greater len h than the bearing surface 83 of the mem er 72 to take care of this greater movement. \Vhen the member 8 is removed from the bodies the springs 89 will forcevthe member 78, roller 68 and members 69 and 71 outwardly until the end flanges 77 engage the end flanges 82 of the members 70 and .72 which engagement prevents the rollers from becoming disconnected from the bodies.

Should it be desired to remove the rollers 68, the plate 88 and the plates 87 which are secured to it are first removed, the springs 89 then compressed and held compressed by means of a wire or tool engaging perforated lugs 92 formed on the spring seats 90 and 91 and when so held are removed, after which the member 78, rollers 68 and members 69 p and 71 are removed as a unit.

When the adjacent ends of two bodies of an articulated unit are constructed in accordance with the invention and are operatively connected together, and the member 8 is interposed therebetween in accordance with the invention, a safe, unobstructed and weather-proof passageway is provided between the bodies, rega'rdless of the position the bodies may assume relative to each other or to the truck.
